Streamline your kitchen with the Siemens SN25M231GB dishwasher.

Finished in white, this dishwasher washes up to 12 place settings and has an excellent A+ energy efficiency rating. The SN25M231GB features 5 programmes and 2 special options, including:


  • pre-rinse (good for infrequent use)
  • intensive 70°C wash for heavily soiled items
  • auto 45-65°C uses sensors to provide the optimum clean
  • economy 50°C uses just 12L of water per cycle

A thoughtfully included Intensive Zone area lets you place heavily soiled items in the lower basket, and at the same time put fragile items in the top.

Rated 4 out of 5 by Good dishy Does all it says ....quiet, we had anticipated a good product and we're not disappointed....happy to recommend the product 28 July 2015
Rated 4 out of 5 by Siemens SN25M231GB Overall good - small issue is that if the cutlery basket is in, you lose space for stacking plates and it makes a dramatic gulp when it begins to empty! These are minor points, dishes come out clean and dry, think its good for the money 28 July 2015
Rated 5 out of 5 by Stunning for the price point Really pleased with this item having had it for a month, was thinking of getting a Bosch but this seems to beat it hands down for the price point. The controls and display on the front are clear, easy to use and make it look more expensive than it really is. Installation was easy, the instructions could be better (lots of different pages, leaflets etc.) but in the end there is only water, waste and power to connect. Salt & Rinse aid are easy enough to sort out too. Inside there is plenty of space, nicely laid out. The tablet dispenser can be a little fiddly but not had a problem so far. Dishes come out squeaky clean and not had to rewash anything so far. 22 July 2015
Rated 5 out of 5 by Good product Very easy to use, added bonus is the spray nozzle for bigger items. You take out the top tray, fit the nozzle and you can then load bigger items for washing, eg: bigger baking trays and roasting tins. Very quiet machine and it has a half load option. 21 July 2015
Rated 4 out of 5 by happy customer Really happy with this machin. Has a good selection of programs. My dishers, come out clean. Would recommend. 14 July 2015
Rated 5 out of 5 by Why I chose this dishwasher. With so many dishwashers on the market - why did I choose this one? Our last two dishwashers have been Bosch and I have been very pleased with them. I never had any doubt that when the time came for a replacement I would choose another Bosch. The day came when I had to start the search. I looked at the Bosch range but the reviews were not good - this was such a disappointment. I decided that rather than just picking another dishwasher without knowing anything about it I would search the JL website by 'highest reviews'. I also had a budget - £300. This Siemens dishwasher came out on top. I couldn't believe that I could actually buy a top rated dishwasher made by Siemens for the budget I had set myself. I had certain criteria that the dishwasher had to have - a timer for night time use, very quiet, digital display, a 'sensible' selection of programmes. This dishwasher fulfilled all the above criteria. Ordering on JL website was as easy as could be. The dishwasher came when promised. So what is it like in actual use? Just as I had expected. It is very quiet - we hardly notice it being on if we happen to run it while we are around, but mostly I run it overnight to make use of cheaper electricity. Very easy to use - the controls look complicated but they are very simple. The look is very sleek. The layout inside is almost identical to our previous Bosch - perhaps if I was being really picky I would prefer the white inside to this grey one, as it is easier to see what's what, but on the whole the layout is good. The cutlery basket is clever in the way that it slides along either rung of plate racks on the bottom shelf - very useful. Personally we didn't get on with the knife rack on the top left. Luckily this knife rack is detachable so after a couple of weeks we just removed it. So are we pleased with our choice? Very. It is the right machine, the right manufacturer and the right price - and even better it came from John Lewis! 11 July 2015
Rated 3 out of 5 by Ultimately disappointing machine Our experience here is a case of two different stories; very impressed by John Lewis, really ultimately disappointed by the dishwasher, which I would describe as no more than 'OK'. John Lewis were excellent; the first machine (same model) dispatched to us developed a fault after 3 weeks and John Lewis replaced it with minimal fuss. The new machine is fault-free (after six months), but the cleaning results are nothing special (and, yes, we do use salt, rinse aid and a reputable brand of detergent, and we clean the filter!), and often mugs in particular need to be returned to the machine for a second attempt to get them clean, usually with results no better than the first time. We've owned other dishwashers before; whilst this dishwasher IS better than the cheap Beko machine we had when money was really tight, but inferior in terms of cleaning to the inexpensive Hotpoint we had before that. So, in summary: John Lewis, 5/5; Siemens dishwasher, 3/5 (could do much better). 08 July 2015
Rated 5 out of 5 by Great product! Our trusty old Zanussi died after 18 years, so we searched the JL site for a replacement, and decided on this as the reviews were all excellent. It has proved to be a worthy successor. It washes and dries everything well.No more pre-rinsing needed. We can fit plenty in, and find the two tier shelving on the top rack useful for cups/mugs and glass tumblers. We can even fit the wine glasses in safely now, thanks to the clever V shaped shelf edges that stop them toppling. The knife rack is handy too. The longer cycles took some getting used to, at least 2 and 1/2 hours...and the Eco cycle is 3 and 1/2 hours, but it seems that all dishwashers are the same these days. There is a quick cycle of 45 minutes...which we are yet to try. It is much quieter than our old machine. A bonus is that it turns itself off at the end of the programme, so happy to leave it overnight. We decided to plumb it in ourselves, which was straightforward...except that they included a spare door seal, and we thought from the instructions that it needed fitting....customer services soon put us straight! Once again, a great product and efficient service from John Lewis. 07 July 2015
